Objective:To explore rational surgical treatment for childhood nail matrix nevi.Methods:A retrospective analysis was conducted on clinical data from 35 children with pathologically confirmed nail matrix nevi, who received surgical treatment in Children′s Hospital of Chongqing Medical University from September 2015 to March 2019. Different surgical approaches were adopted according to the site and width of lesions. For lesions with a width of ≤ 3 mm, the nail bed and nail matrix lesions were directly excised with 1-to-2-mm margins and sutured in 11 cases. For lesions with a width of > 3 mm, one of the following 3 surgical procedures was selected by the children′s parents: (1) shaving of nail bed and nail matrix lesions under a microscope at ×8 magnification (8 cases) ; (2) excision of lesions followed by full-thickness skin grafting on the periosteum of the phalanx (8 cases) ; (3) excision of lesions of the second to fifth fingers followed by transfer of skin flaps from the thenar muscle area and full-thickness skin grafting (5 cases) , or excision of lesions of the thumb followed by abdominal-wall flap transfer (3 cases) . The patients were followed up for 12 months, and clinical efficacy was evaluated.Results:During the follow-up, no recurrence occurred in the 11 cases receiving direct excision and suture, with good appearances and longitudinal linear scars on the nail. Among the 8 cases receiving shaving therapy under a microscope, 4 experienced relapse during the follow-up of 6 - 12 months, and the nail/toenail plates were rough and poor in lustrousness in the other 4 without recurrence. No recurrence was observed in the 8 cases receiving excision of the lesions and full-thickness skin grafting, of whom 1 experienced skin graft necrosis, and skin grafts survived with obvious pigmentation in the other 7 cases. Among cases receiving excision of the lesions combined with transfer of skin flaps from the thenar muscle area or abdominal-wall flap transfer, no recurrence was observed, and all transferred flaps survived; good appearances, nearly normal color and gloss of nails were obtained in the cases after transfer of skin flaps from the thenar muscle area, while the color and gloss of postoperative nails were markedly different from those of normal nails in the cases receiving abdominal-wall flap transfer.Conclusion:For nail matrix nevi with a width of ≤ 3 mm, direct excision and suture with 1-to-2-mm margins are recommended; for those with a width of > 3 mm, excision of lesions combined with full-thickness skin grafting, transfer of skin flaps from the thenar muscle area or abdominal-wall flap transfer is recommended; the shaving procedure under a microscope should be used with caution.

<p><b>OBJECTIVE</b>To analyze the changes in body growth, learning and memory capabilities, exercise capacity, and the level of growth hormone (GH) in mice suffering from severe burn.</p><p><b>METHODS</b>One hundred and four healthy BALB/c mice aged from 3 to 4 weeks were divided into normal control group (NC, without treatment) , 7 s burn group (inflicted with 20%TBSA deep partial-thickness burn on the back), 10 s burn group (inflicted with 20%TBSA full-thickness burn on the back), and negative control group (simulating the treatment of two burn groups without injury) according to the random number table, with 26 mice in each group. The body weight, body length, and tail length of 8 mice in each group were measured before burn. Respectively 6 mice of two burn groups were sacrificed on post burn day (PBD) 1, 3, and 7 for determination of serum level of GH with enzyme-linked immunosorbent assay kit. The remaining 8 mice in each of the two burn groups were raised to adulthood. The body weight, body length, and tail length were measured on PBD 62, and the increased percentages of body weight, body length, and tail length were calculated. Morris water maze tests, including escape latency on PBD 66, 67, and 68, frequency of stepping over the platform location and proportion of staying time in the target quadrant on PBD 69, were used to examine the learning and memory capabilities. The time of loaded swimming and the time of pole-climbing on PBD 70 were used to assess the exercise capacity. Above-mentioned indexes were also determined in the two control groups at the same time points. Data were processed with one-way analysis of variance; Welch test was applied when equal variance was not assumed; independent samples t test was applied for paired comparison.</p><p><b>RESULTS</b>(1) The level of GH of mice in 7 s burn group on PBD 1 [(3 021 ± 506) pg/mL] was lower than that of group NC [(3 728 ± 412) pg/mL, t = 2.656, P < 0.05], while on PBD 3 and 7 [(3 098 ± 503) , (3 199 ± 275) pg/mL] they were close to those of group NC [(3 872 ± 785), (3 301 ± 600) pg/mL, with t values respectively 2.033 and 0.379, P values all above 0.05]. The levels of GH of mice in 10 s burn group on PBD 1, 3, and 7 were respectively (2 859 ± 447), (2 707 ± 151) , and (2 666 ± 222) pg/mL, which were lower than those of group NC (with t values respectively 3.504, 3.571, 2.429, P < 0.05 or P < 0.01). (2) The increased percentage of body weight, body length, and tail length of mice in group NC, 7 s burn group, and 10 s burn group were respectively (155 ± 22) %, (46 ± 6) %, (63 ± 10)%; (112 ± 57) %, (32 ± 12) %, (40 ± 15) %; (106 ± 36) %, (30 ± 8) %, (32 ± 7) %. The increased percentage of body weight of mice in 7 s burn group was close to that in group NC (t = 1.997, P > 0.05), while the increased percentages of other indexes of mice in the two burn groups were lower than those in group NC (with t values from 3.092 to 6.910, P values all below 0.01). (3) The escape latency values of mice in 10 s burn group on PBD 67 and 68 were respectively (33 ± 12), (33 ± 11) s, which were longer than those of group NC [(20 ± 8), (20 ± 7) s, with t values respectively 2.421 and 2.692, P values all below 0.05]. The frequency of stepping over the platform location of mice in 10 s burn group [(1.6 ± 1.8) times] was close to that of group NC [(3.2 ± 1.5) times, t = 1.989, P > 0.05]. The proportion of retention time in the target quadrant of mice in 10 s burn group [ (28 ± 7) %] was shorter than that of group NC[(48 ± 16)%, t = 3.076, P < 0.01]. The escape latency of mice in 7 s burn group on PBD 67 [(30 ± 7) s] was longer than that of group NC (t = 2.659, P < 0.05). The frequency of stepping over the platform location and the proportion of retention time in the target quadrant of mice in 7 s burn group [(2.0 ± 1.1) times, (36 ± 11) %, respectively] were close to those of group NC (with t values respectively 1.930, 1.670, P values all above 0.05). (4) The time of pole-climbing [(30 ± 11) s] and the time of loaded swimming [(38 ± 39) min] of mice in 10 s burn group were shorter than those of group NC [(47 ± 11) s, (122 ± 74) min, with t values respectively 3.108, 2.868, P < 0.05 or P < 0.01]. The time of loaded swimming of mice in 7 s burn group [(47 ± 12) min] was shorter than that of group NC (t = 2.855, P < 0.05), while the time of pole-climbing [(33 ± 14) s] was close to that of group NC (t = 2.044, P > 0.05).</p><p><b>CONCLUSIONS</b>For mice, severe burn can delay body growth, decrease the learning and memory capabilities, decrease exercise capacities, and reduce the serum level of GH.</p>

BACKGROUND:In recent years, tissue engineering has made great progress, and skin tissue engineering is especialy noteworthy. Artificial dermis (PELNAC) is relatively used widely, but there is a lack of relevant reports on wound repair in children. OBJECTIVE:To investigate the clinical efficacy of Pelnac? METHODS:In a retrospective study, 22 patients with the wound of severe trauma were treated with Pelnac as skin graft dressings on treatment of the wounds of severe trauma in children. ? graft, negative-pressure wound therapy and split-thickness skin graft as experimental group (Pelnac? group), and another 19 patients treated with granulation formation dressing and split-thickness skin graft as control group. We colected data including the graft livability, the required re-operative times and the epithelization time after the skin graft. During the folow-up, the skin color and texture of survival skin, subcutaneous fulness, scar hyperplasia and the joint function were also evaluated. RESULTS AND CONCLUSION: In the Pelnac ? group, the graft livability was up to 90% within 10-14 days after grafting. The secondary split-thickness skin graft was required in two cases in the Pelnac? group and in eight cases in the control group. There was a significant difference in the graft livability (P < 0.05). The average epithelization time after the skin graft was (13.86±3.09) days in the Pelnac? group, which was significant shorter than the control group, (19.10±4.62) days, after the first time operation (P< 0.05). During the 10 months folow-up, the survival skin color and skin elasticity in the Pelnac? group was significantly better than that in the control group (P< 0.05). Better subcutaneous fulness and milder scar hyperplasy in the injured sites were obtained in the Pelnac? group compared with the control gorup. Five cases had certain joint function limitation in the Pelnac? group, compared to 10 cases in the control group, with a significant difference (P < 0.05). Artificial dermis Pelnac? has a stronger anti-infectious ability and higher graft livability. Pelnac? graft combined with negative-pressure wound therapy, granulation culture and split-thickness skin graft can shorten the epithelization time, improve wound healing and aleviate harm to the joint function after the skin graft.

ObjectiveTo assess the diagnosis and treatment of staphylococcal scalded skin syndrome (SSSS)in children.MethodsA total of 177 children whh SSSS were eligible for this study.Clinical data were retrospectively reviewed to assess the patients' age and geographical areas,predisposing factors,prodrome,clinical features,results of laboratory examination(including bacterial isolation and drug susceptibility test),treatment and prognosis.ResultsThe median age at onset was 23 days past 15 months.Infants aged 1 to 3 years were the most commonly affected population.The male to female ratio was 8:9.SSSS occurred in summer or autumn in 71.2% of the patients.Most patients came from countryside.Of these patients,148 (83.6%) had no definite inducement,13 (7.3%) had fever or cold history before the occurrence of SSSS.Skin lesions often began in the face(71.6%).Almost all cases presented with erythema and blisters.Abnormal myocardial enzymes were observed in 104(80.6%) of 129 patients,and Staphylococcus aureus was isolated from 38.7% of 142 patients.Susceptibility testing of 21 Staphylococcus aureus isolates from patients in the past 3 years showed that 95.2% and 95.0% were sensitive to cephalosporins and amoxicillin/clavulanic acid respectively.Double-antibiotic therapy was effective in 72.9% of the patients.Intravenous gamma globulin was given to 36.2% of the patients in the early stage.Myocardial-protecting drugs were also administrated early in patients with abnormal myocardial enzymes.All the patients healed without scarring.ConclusionsFor infants with acute facial erythema and exfoliative skin lesions,SSSS should be suspected and timely antibiotic treatment should be given.Cephalosporins and semi-synthetic penicillins are effective and the first choice for the treatment of SSSS.Meanwhile,early addition of gamma globulin and myocardial-protecting drugs may be beneficial to disease recovery.
Résumé
Cantharellus Adans. ex Fr., a member of the Cantharellaceae, Cantharellales, Homobasidiomycetes, Basidiomycota, is a widely distributed macro-fungal genus with an independent evolutionary lineage. It currently includes 65 species, of which 9 were recorded in China. In this article, research history of the genus was briefly reviewed and some controversial conclusions, especially the demarcation and naming of some taxa, discrimination among similar species, problems on C. cibarius Fr. and C. tubaeformis Fr.: Fr. complex, as well as their ecological conservation and bionic cultivation, are discussed based on the authors’ findings. Proposals for further research on biodiversities and sustainable utilizations were put forward at last.

Objective:To study the technique of treatment of infant hand congenital syndactyly. Methods:All cases were from 6 months to 2 years old .In these cases, the fingers were separated by using the serrated flap and new weh were created deeply and widely by using rectangle or triangle inter-phalangeal flap at dorsal and palmaris. The skin-defected areas were covered with full-thickness skin grafts and the fingers were fixed using small splints. Results: All 38 cases were primary healing except that partial necrosis of skin graft in 10 cases which were healed after dressing change. The scar of 7 Cases were relieved by using small splints at night and glucocorticoid injection treatment. 1 case which finger was bent because of scar was operated again and another one had not any management. Followed up 6 months~2 years,37 cases had good features and functions except one case without dealed. Conclusion:It is feasible that treatment of hand congenital syndactyly durying infancy.
